Hydraulic Gear Extension System Schematic
The main landing gear of the DA 42 is extended with three hydraulic cylinders. The
following schematic Figures show the system conditions for each operating mode.
In Figure 1 the extension of the landing gear is shown. To reduce the amount of pumped
hydraulic fluid during this operation, the return flow is partly led into the feeding flow of
the system.
The Figure below shows the system status when the landing gear is extended. All hydraulic
cylinders are under high pressure.
